Application led .Tune 16, 1909. Serial' No. *502,564.

lTo allwwm it mag/ concerm Be it known that I, FREDERICK A. Paar-1L, a citizen of the UnitedStates, and a resident of the borough ofManhattan, city, county,

and State of New York, have invented certain new and useful Improvements 1n Knockdown Barr-els, of which the following It seeks to provide a barrel combining a high degree of 'strength and durability with great economy of production. The inven' .tion consists of the features .hereinafter set forth and specified in the claims.

ln the accompanying drawings forming part of this specification Aand in which like reference numerals designate corresponding parts, Figure l is a perspective View of ay barrel embodying one form of' theinvention; Fig. :2 is a sectional view of the top headzFig. 3 is a fragmental view in sectional plan 'through the barrel body at one of the clips ;v Fig. l is a perspective view of a clip; Fig. 5 isa lplan view showing the fabric ofwhich'the barrel body is made; Fig. 6 is a vertical section through the bar- -rel body and showing the position of thev heads; Fig. 7 is a view similar to Fig. 6

showing some of the details modified.; andv S is an enlarged detail 1n lsection of the -barrel body and bottom head shown 1n Fig. 7.

ln accordance with the present invention spaced transverse wires extending across all the staves on one side and stap-led thereto, and a plurality of spaced transverse wires extending across all the staveson-the opposite side and sta-pled thereto. Heretofore various forms of knock-down barrels have been proposed. These have generally been expensive to make. lacking in strength, d urability and rigidity, or otherwise impracticable oi objectionable. Among these earlier suggestions it has been 'proposed to malte a knock-down barrel of a body fabric consisting` of staves and transverse wires, but these have not been satisfactory for various reasons.. If thewires and staves were woven together as was proposed, then the barrel lacked rigidity and firmness, there Specication of Letters Patent.

Patented J an. 3, 191] being nothing to hold the individual staves in place, except the frictional binding of the-v woven wires, yand this was generally not sufiicient to reliably prevent the longitudinal slipping of the staves, or some of them. Again, a'woven fabric is likely to be too flexible to make a barrel of sufficient rigidity, and is expensive and difiicult to construct. It has also been proposed to use a body fabric having outsidewires only, which were stapled to the staves. In this case there were `no inside wires whatever, and consequently here was nothing to effectually resist outside pressure-or shocks which tended to collapse the barrel, except the strength inherent in the material of the staves themselves. .f

The present invention obviates the objections pointed out' and it does so by the very economical, eiicient and practicalarrange- *ment first above-specied.. The completed .barrel largely depends fory its rigidity and.

durability upon the location and arrangement of the wires inside and outside and the manner of securing them in place, and because of the eiiicient arrangement of these wires, it is' entirely practicable to use staves only g .afan inch iii-thickness, cut from what has heretofore been practically waste material occurring as a by-product.

-Referring now'inore particularlyY to the specific features, as shown in the drawings, l is ,the body of the barrel in tubular form. It is made from the fabric shown in Fig. 5 which comprises the staves 2, the outside wires 3, el, 5 and 6 and the inside wires 7, 8.

-9 and 10 rigidly secured to the staves by staples l1. The fabric may be rapidly and economically made in a machine to which the staves, wiresand staples are fed.l The outside wires extend across the'outside of all the staves andthe inside wires extend across the inside of all the staves, and thus are not woven-or twined around the staves. The wires on the outside preferably register with those on the inside, as shown in Figs. '1, 3, 5 and 6 and at top and bottom in Fig. 7.

This makes it feasible to secure the register- .ing wires by the same staplesand is econom- Yical and effective in its result.

Y When vthe completed fabric has been formed into a tube for the barrel body, its meeting edges arefirmly secured by suitable means. ln the'preferable arrangement the 5.5.'.- close'together'or as far apart as desired and lWires have ends *projecting vbeyond the edges f of the fabric, and the-oppositely proj ecting` Wire ends are suitably secured-togetlier to maintain the barrel -body in rigid forin.`

Proj ectiiig Wire ends are shown at the left in Fig. 5. A satisfactory Way of securing o ppositely projecting Wire ends is shown in Fig.3. rIlliere the tvire ends are all brought outsidethe barrel between the meeting edges of the fabric, and one end of Wire'4 is twisted-"With the oppositely projecting end ofiivir'e 8. The other end of Wire 4 is twisted With the remainingy oppositely projecting lendof Wire' 8. lOf course this arrangement maybe varied and other'means for holding together the meetingedges of the fabric may be used. -It is -sometimes desirable to ein-l ploy additional means to prevent the meeting edges of the fabric from bulging out- Ward'somewhat. For this purpose clips or .bridge pieces, 'such as the clip 12, may be used. The clip l12 comprises a thin metal v,plate having a perforation 13, and upt-urned ends 14 and 15 each vhaving a notch 16. These clips are located on one side of the staves acrossthe meeting edges of the fabric 18, and the upper head 19 is supported upon the outer side of inside Wire 7, being held in placel by staples 21. In Figs. 7 and 8 the ldwer'head 22 is provided With an annular vgroove 23 'to` receive the Wire 10 and thus supportihehead, and is held in place by staples 24 -fWhich span the Wires 6 and 10,'I

Either -arrangement may be used for the bottom head'. `Instead of having the inside and outside Wires in register .with each other,

'they may bearranged out of register, if

desired* This is shown in Fig. i with refer ence to the intermediate-Wires 4, 5 and 25.

It Will, of course, be understood that the number of Wires on either side of the staves may be considerably varied, but in any case, in'order to secure the desired results there l should be a plurality of Wires on each side 'of the v"staves and some of these should be vbody fabric. It is preferable, also, to have the *inner Wires somewhat larger than the outer Wires. The staves may be arranged as may be rectangular andA iiat, or have any other desired. shape. 'Anion'gthe advantages of the inner end Wires 'Rand 10, are thattheyvprovide secure and reliable means for .supporting-the heads f' in place againstnwardly directed pressure, that theyvfacilitate the formation of the body fabric into tubular. form in setting up the barrel, and that they add strengthv and rigidity to the ends of the barrel, the upperv "located at or near the top and bottom of the Wire 7 being especially serviceable in this respect when the barrel is filled and shipped with a cover of burlap or other textile fabric instead of a head. It will, of course, be

understood that hat, flexible metal bands are the equivalent of the Wires, and the term wires is herein used in this sense. r l
